| Abstract: |
| In order to expound the mechanism of steel-band bolting support,the interaction of steel-band and surrounding rock is particularly analyzed.By numerical simulation in using of soil and rock engineering software FLAC2D,the supporting process and some parameters that affecting the supporting effect are analyzed.The research results show that the steel-band bolting supporting can control the surrounding rock deformation effectively;the steel-band's parameters have remarkable functions to the support effect.Therefore the practical project should adjust measures to local conditions,Choice of steel-band must match the bolt's parameters,in order to exert the function of steel-band,and it must be installed reasonable. |
